Definition
By Mayo Clinic staffRickets is the softening and weakening of bones in children, usually because of an extreme and prolonged vitamin D deficiency.
Vitamin D is essential in promoting absorption of calcium and phosphorus from the gastrointestinal tract, which your child needs to build strong bones. A deficiency of vitamin D makes it difficult to maintain proper calcium and phosphorus levels in bones.
If a vitamin D or calcium deficiency causes rickets, adding vitamin D or calcium to the diet generally corrects any resulting bone problems for your child. Rickets due to a genetic condition may require additional medications or other treatment. Some skeletal deformities caused by rickets may need corrective surgery.
